This listing is for a fully built and tested Universal Paste Extruder I have designed for RepRap 3D printers. It also includes a set of syringes and needles to get you started.

The BOM and all source files are here – http://www.thingiverse.com/thing:20733

It has a powerful NEMA17 motor, with high gearing and a belt drive for mechanical syringe compression.

It allows you to experiment with various pastes on your 3D printer without the need for any air compressor equipment or valves etc.

It simply uses the existing Extruder motor output from your printer’s electronics.

You can print with Ceramic Clays, Silicone, Sugar pastes, Chocolate, Frostings, Masa Harina, and all sorts of other food’s or pastes that can be extruded through a syringe.

Each fully built and tested extruder comes with 8 x centre slip syringes; these are great for foods and pastes and 3 x luer lock Syringes. This type allows the fitting of removable needle ends for ultra-fine printing (great for ceramic printing).

Also included are 5 x 0.6mm blunt needles and 5 x 0.4mm needles, these will need to be cut down for best results.

More information about its design and use can be found on my Blog here – http://www.richrap.blogspot.co.uk/2012/04/universal-paste-extruder-ceramic-food.html

This is an experimental extruder; please take a look on my blog for ideas. If you are unsure if it will fit on your 3D printer please send me a message.

It’s designed to fit on a normal Prusa / Greg X carriage and has the standard extruder fit-spacing for M4 bolts as per a normal Greg/Wade extruder.

Alternatively it is also designed to fit on my Quick-Fit extruder X carriage, so you can swap over extruders in just seconds – see on Thingiverse here  – Quick-Fit X Carriage Thingiverse – http://www.thingiverse.com/thing:19590
